Yes, that's not very hard and a good idea.

If you use kernel modules that are not part of the stock kernel (like 
nvidia , catalyst, vhba-modules ) additonal steps are needed.

For now i'll assume you don't have such modules.

- Almost every time an arch wiki page states "install program" , it 
means one of 2 things :
install with pacman
install from AUR with makepkg

The lts kernel is in official repos, so you can install it with pacman.

- to be able to boot the lts-kernel , you have to add an entry to your 
bootloader config for it.
Grub stores that info in grub.cfg , grub page lists where it can be found.

As Root :
copy grub.cfg to something like grub.cfg.original
open the file with your fav tekst editor.
Copy the entry for arch stock kernel to a new entry and change what is 
needed to have that boot the lts-kernel instead of the stock kernel.

Reboot and test if it works.
